The NCP551SN28T1G from onsemi is an ultra-low-power 2.8V fixed-output LDO regulator capable of 150mA. Its exceptional 8µA quiescent current and 0.15V dropout at 10mA make it one of the most efficient choices for battery-powered applications. The compact 5-TSOP package fits tight layouts.
- Ultra-Low Quiescent Current: 8µA dramatically extends battery life.
- Very Low Dropout: 0.15V at 10mA maximizes usable battery capacity.
- 150mA Output: Sufficient for most low-power sensors and MCUs.
- Compact TSOP Package: Ideal for miniaturized designs.
Ultra-Low-Power Wearables
With only 8µA quiescent current, it's perfect for always-on health monitors and smart rings.
Battery-Powered Remote Controls
150mA output and low dropout ensure reliable operation from nearly depleted batteries.
Portable Audio Players
Clean 2.8V supply for audio codecs and amplifiers, minimizing noise.
Wireless Sensor Networks
